6813 frame - 2 Pole Stiff Shaft Design

Siemens 6813 frame 2 pole stiff shaft motor allows induction motor users to operate a motor and drive application up to 5000 HP without concern related to sub synchronous speeds.

This product offers a smaller frame with a better price and lead time for applications requiring a stiff shaft designed motor.

The stiff shaft 6813 frame allows for operation on a VFD over a larger speed range by designing out the critical speed and saves the customer time and money.

  • Expanded stiff shaft motor capability for 2 pole 680 frame family motors

  • Does not require bearing flood lubrication

  • Increased power with up to 5000 HP while improving the motor lead time



Review the key benefits below:

Optimized Application

  • With a 2 Pole Stiff Shaft design, your application can operate in a wider speed range creating more application flexibility and system efficiency.

  • A modular enclosure design concept provides more options to meet the application requirements.  Available in WPII, TEAAC and TEWAC enclosures.

Increased Power Density.

  • With up to 5000 HP available as a 2 Pole Stiff Shaft design, users can enjoy an almost 70% increase in stiff shaft power and value in the same frame family.


No flood lubrication required, no problem.

  • With our new bearing design, we can offer lower bearing temperatures which help keep your project on budget by eliminating the need for extraneous lubrication systems.

Tight budget? We’ve got you covered.

  • Improved design offers more power on a smaller frame allowing for up to 20% savings compared to previous offering

Sensitive Project Timeline?

  • Smaller frame, up to 15% shorter lead time to help keep your project on time and on budget





HIGH SPEED

Why high speed?

Siemens utilizes standard components in a unique way to operate a motor at speeds above a traditional 3600rpm design in order to optimize the system efficiency and performance.

The conventional high speed motor solutions offers flexible designs suited to most direct drive applications, simple installation, reliable, reduced maintenance, low operating costs, and environmentally friendly.



Review the key benefits below:

Need more speed? We can help

  • By offering induction motors up to 6000rpm, the application requirements can be met with less installed equipment.

Tested Reliability

  • Each rotor is balanced on our state of the art high speed balancer to ensure reliable and safe field operation.



Simplified Maintenance

  • The elimination of highly specialized components like active magnetic bearings and permanent magnet rotors allows for easier and more familiar servicing

Reduced Footprint

  • This product allows for the elimination of system equipment which will help reduce installation and maintenance costs by helping to keep the project on schedule and on budget

Design Flexibility

  • With the ability to offer this product on multiple frame sizes, including our 500, 580 and 680 frame families, Siemens can partner with you to design the right motor for your application.
